Can you provide content please.

Yes thats it. But we need size of the flyer to upload if we use the 5000 x 5000 pixel standard in the Design crowd to upload it is for the Logo Design and it is Square type ,Now some of the flyers size sample i made is half of the letter size paper and sometimes it is back to back or other is three folded . so which one of those we will fit to layout for your Flyers?
